Abstract

In two celebrated experiments of quantum mechanics, the Stern-Gerlach (SG) and Heisenberg microscope (HM) experiments, the electron spin sz and spatial r coordinates are measured separately. In this paper, the combined SG+HM experiment is proposed to measure the full electron coordinate x={r,sz}. To this end, noninterfering and (virtually) simultaneous SG and HM experiments are proposed to apply to the individual fragments A and B of an entangled dissociating system A-B. The theoretical description of a spin-collapsed and partially spatially collapsed state of the SG+HM experiment is given for the prototype "perfectly"entangled system, the dissociating H2 molecule.
